Curated OER
AP: Chapter 42: Circulation & Gas Exchange
Immerse biology learners in circulation and gas exchange for both simple organisms and higher animals. Six pages of short-answer questions and labelling of the human respiratory system are included. This assignment was written for an...
Curated OER
Circulatory Systems
A slideshow that covers the all-important details related to basic human circulation. The reasoning for exchange of material methods is presented and then labeled diagrams of the main human transfer systems are shown, along with...
Curated OER
Gas exchange: Respiratory Systems
The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism. Students are able to learn about the...
Curated OER
Gas Exchange And Respiratory Systems.
Explore structures within the realm of gas exchange in terrestrial and aquatic life. The excellent, labelled diagrams and clear descriptions help your students view the different structures and adaptations that have developed. The 29...

Changing Planet: Withering Plants - Stressing Over Lost Water
Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...
Curated OER
Gas Exchange
In this biology learning exercise, students examine the process of respiration and specifically look at the biochemistry of gas exchange at the alveoli.
Curated OER
Respiration and Gas Exchange
In this body systems worksheet, learners complete a word equation for respiration. Students draw and label the human respiratory system. Learners draw a diagram of the movement of oxygen and carbon dioxide in the air sacs.
